Filed:

Jan 11, 2000

Appl. No.:

09/481085

Inventors:

Gene A. Bornzin - Simi Valley CA
Paul A. Levine - Santa Clarita CA

Assignee:

International Classification:

A61N 1368

US Classification:

607 28, 607 11

Abstract:

An implantable dual chamber stimulation device provides a novel detection scheme for automatically detecting atrial capture and performing an atrial pacing threshold assessment. The stimulation device preferably waits until the patient is at or near rest and monitors the patients P-wave activity to determine an detection window where a next P-wave is expected to occur. The stimulation device then delivers an atrial pulse prior to the next detection window, and monitors the window to determine whether a P-wave occurs therein. If a P-wave does not occur, then atrial capture is present, while occurrence of a P-wave indicates absence of atrial capture. If atrial capture is absent, the stimulation device automatically determines an appropriate atrial pacing threshold by monitoring the detection window while adjusting the stimulation pulse energy level. Advantageously, the present invention further employs a âbottom-upâ adjusting scheme which starts at a low energy level, below the expected atrial pacing threshold, and increases the energy level until atrial capture is detected, thus saving energy and further avoiding corruption by large polarization signals. The latter feature is compatible with the present detection scheme and conventional evoked response detection schemes.

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 108

US Classification:

607 30, 607 32, 607 59, 607 60

Abstract:

To permit remote programming of implantable cardiac stimulation devices such as pacemakers, a central device programmer is provided in conjunction with a network of remote telemetry units for use in patient homes or in remote clinics. To reprogram a device implanted within a patient, a physician enters programming commands within the central programmer which relays the programming commands to a remote telemetry unit in proximity to the patient. The remote telemetry unit, in turn, forwards the programming commands to the implanted device. In this manner, the patient need not return to the physician for reprogramming of the device. Remote telemetry units may be provided within patient homes, clinics, hospital emergency rooms, hospital patient rooms, and the like. Depending upon the implementation, different levels of programmability may be permitted depending upon the degree of supervision of the patient. For an unsupervised patient, limited programmability is permitted.

International Classification:

A61N 1372

US Classification:

607 28

Abstract:

An implantable cardiac stimulation device applies pacing stimulation pulses to a heart and senses evoked responses to the pacing stimulation pulses. A pulse generator applies the stimulation pacing pulses to the heart in accordance with a pacing configuration. A sensor control selects an evoked response sensing electrode configuration from among a plurality of evoked response sensing electrode configurations in response to the pacing configuration. A sensor is then programmed to sense the evoked responses with the selected evoked response sensing electrode configuration. In accordance with a preferred embodiment, signal-to-noise ratios obtained with the various electrode configurations are used to select a best electrode configuration for sensing evoked responses.

Abstract:

An implantable dual chamber stimulation device provides a novel detection scheme for automatically detecting atrial capture and performing an atrial pacing threshold assessment. The stimulation device preferably waits until the patient is at or near rest and monitors the patient's P-wave activity to determine a detection window where a next P-wave is expected to occur. The stimulation device then delivers an atrial pulse prior to the next detection window, and monitors the window to determine whether a P-wave occurs therein. If a P-wave does not occur, then atrial capture is present, while occurrence of a P-wave indicates absence of atrial capture. If atrial capture is absent, the stimulation device automatically determines an appropriate atrial pacing threshold by monitoring the detection window while adjusting the stimulation pulse energy level. Advantageously, the present invention further employs a “bottom-up” adjusting scheme which starts at a low energy level, below the expected atrial pacing threshold, and increases the energy level until atrial capture is detected, thus saving energy and further avoiding corruption by large polarization signals. The latter feature is compatible with the present detection scheme and conventional evoked response detection schemes.

Abstract:

A system and method determining physiological status of a patient. A determination is made whether the patient is sleeping. The amplitude and change in voltage over time of any intramyocardial electrogram is measured for a right ventricle and a left ventricle of a heart of the patient for a predefined number of heartbeats at a specified time interval in response to determining the patient is asleep. The measurements are averaged for the right ventricle and left ventricle. The averaged measurements are transmitted to a receiver for communication to an intended recipient.
